Short answer...chill
@Neil (नील/Нил)
Life has its own pace, everything will fall in place when they're supposed to, the only thing in your hand is working on yourself. Everything else is beyond your control.
1. Getting emotional is what we as a human are biologically supposed to do don't get influenced by all these incels and redpill bullshit. Cry if you feel like, you'll feel good.
2. In short term...don't get stuck in loop of regrets, you'll mess up your present. Rather note down one or two "takeaway" from those regrets so that you don't have the same regret twice. If it was a failed relationship then these could be red flags of both you and your partner and if it was something related to academics then may be some topics that you need to work on.
In long term...find something bigger/better than the regret. We're very simple machines, the day you'll find something better the brain would overshadow the older regrets.
3. You either stop doing things for others or do everything possible without expecting anything from them.
Western philosophy, Indian Shruti...whatever you consult, this is only way to "love", they day you'll start expecting anything in return you'd just start tormenting yourself.
4. • Focus on health, this 20-30 year bracket is the perhaps the best possible window you've to work on it. Nothing hardcore, just diet and some compound exercises.
• Don't miss mental health.
• Give back to your parents in whatever way you can because time runs out pretty quickly and then you realise all the things that you could have done.
• Try not to fall for a girl whom you just like, rather find someone with whom you see both of you helping each other grow.
• Have a hobby that you're insanely passionate about; this is what'll keep you alive. Can be anything from cooking, books, painting, photography to biking to automotive; but you should have atleast one thing for which you're just illogically crazy about...or otherwise you'll turn into a walking corpse.
Baaki chill karo Yaar
