People make me sad

I feel so bad for so many people out there who wernt able to persue what they want. Like you hear about people talking about what they wanted to do but either they never suceeded or never pursued it because they were told they'd fail, because they had a kid and just picked something that gave them no time so the just got by, or whatever. It makes me so sad but theres no changing the past so oh well. The best you can do is just try and do what you want or at least enjoy life I guess
