Umm I would like to share that there have been a mentality shift in me I guess, I'm don't run after things much now, plus I earlier used to see others as competition but now I see them as friends, everyone is good in this world tbh, the more hate you have in your mind the more people will seem bad. Also as you grow especially in my case I went from a 20 yo to a 25 yo,I felt that you started liking more of a slow paced rather than a fast paced life, plus you like to look for peace and @ stability. There can be different mindsets as well but this is what has been in my case.
Also one more thing that friends are not there always and become less and less and you tend to feel lonely and need to be loved by someone special as you age, this is an intense emotion that I felt in the last 5 yrs.
