Anon assesses his life

The purpose of life isn't to make friends. It's to keep powering up as far as you can and then pass on the baton to your children to power up even further to heights you couldn't reach due to mortality.

On a more realistic note, having friends is nice, and the easiest way to make friends is to be successful enough and socially interesting enough and extroverted enough that other people want to interact with you.

However, be warned, the further you age, the more your friendships may either strengthen with time or feel more flimsy to the touch.
