There is always a choice between doing the right thing and doing everything else. All things have an opportunity cost...
Hence long-range thinkers are usually the happiest longterm. No matter what your struggle is, go and take a look at the people over in Palestine, I can assure you it’s nothing like what they face on a daily... just keep it all in perspective. If you do what you can then nobody has a reason to complain.
If you don’t bother being your best when nobody else around you will bother either. Then you get a society full of people who don’t even try... what comes from that? You have to get out there and give it you're all. Even if you don’t see the point of your struggle just yet... the sheer act of working towards a solution is the important part!
