Life can be pretty complicated. Especially because there are no rules to it. As every person and day is different, change and learning comes along inevitably. 

Just like how we are nothing like we were a year ago, our thoughts also evolve, especially in our 20s. Here are some lessons that I learnt in my 20s. 

1. People change overnight.
