I understand what you're going through and how isolating it must be.
I think while not everyone thinks the way you mentioned, many people do. Most people have a core of kindness and want to live good lives while making the world a better place. However, practical considerations often weigh them down, and as you said, no one really talks about these things, even if they are thinking it.
Hi, I am still in my 4th undergraduate year of study.
I don't mean to boast, but I am very smart.
Good for you However, make sure you are not making the mistake of dismissing other people as stupid, which is a trap that those who have above-average intelligence often fall into. Also remember that there are many kinds of intelligence - including emotional and social intelligence. Nurture yourself and your mind as you would nurture a person you love.
I am constantly troubled by the meaninglessness of life. I believe
the only thing making me find it worth living is to fight for some
cause, like poverty or refugees. But, thinking about big issues makes me
feel small and helpless.
It is normal to feel this way sometimes, especially when you are young and trying to figure your your purpose in life. I think it helps to think of life as something organic, evolving, and a gift. Not knowing what you are 'meant to do' can be extremely frustrating and disconcerting - but the solution isn't always to find a purpose. Sometimes the solution is to learn how to become comfortable with discomfort and with uncertainty. Because no matter what you do, these will be a part of life - and it's not a bad thing! It's just a sign that you are human and capable of growth.
It's also completely normal to feel impotent and hopeless when it comes to solving the 'big' issues. The truth is no one person can solve these issues - they are a function of the human collective. But every little bit helps. For example, you may not be able to solve world hunger, but you can begin by donating food to a local charity while slowly brainstorming ways to tackle this at a higher level. One of the mistakes we make when try to make a difference is that we think that only the big actions matter - we do not realise that those big actions would not have existed if people hadn't started somewhere first, often at the grassroots level.
My deep thought about philosophy, causes, meaning of life,
virtuousness has made me distant from everyone. Nobody thinks that deep.
I think about the world problems and how to solve them most of the
time, but nobody around talks about them much, or even think about them.
Everyone is happy.
Do not fall into the trap of thinking that those who are happy do not care about these things - it's usually more that they have made peace with them. Especially as one grows older, people start finding their niche and the figuring out what matters most to them - whether big or small. People also usually don't talk openly about such things, often due to the fear of being judged harshly. As you have already started, start seeking out more like-minded people locally as well as elsewhere. Don't restrict yourself to your immediate friend circle or family. At the same time, keep your mind open - do not look down on those who don't seem to think about the same topics as you do as inferior.
I really don't feel like I deserve the good life I have, while there
are others out there who suffer, specially in the continent of Africa.
This is understandable - it is hard not to feel guilty when we see the suffering of others. But remember that this survivor's guilt doesn't actually help the person you are feeling sorry for; in fact, it often prevents you from taking positive action. I think if you live a comfortable life, a good practice would be to cultivate gratitude, and try to use it to replace the guilt. Say that you are thankful that you have such a good life, and that you hope that you have the strength to help those who weren't as lucky.
The sufferings of the world depress me, and what is more depressing
is how many people don't care about it, and are too involved in their
Something that might help here is that Instead of focusing on the people who don't seem to care about the same things, actively seek out the ones who do. Do not judge or condemn those who don't think the way you do, but try to find others who are like-minded. When you do, talk to them and try to come up with proactive ideas on how you can help. Also try to ask yourself if perhaps you are pending more time, effort, and energy on mentally condemning those who you feel don't care enough - than on actually coming up with solutions to some of these problems. The more we focus on how other people fall short of our expectations, the less capable we will be of actually making the changes we want to bring to the world.
I hope this helps, at least a little. There are some great books that can help - and make sure that you are prioritising taking care of yourself - it's difficult to help others when you are in a bad place yourself. Take care, and all the best.
