Don’t do it, if you don’t feel like it. The most important thing for mental peace is to do what you like. When you do something and you’re not into completely, you’ll end up making a mess out of it. The mess which you might regret later.
The difference between successful and very successful people is that very successful people say NO to almost everything. – WARREN BUFFETT
Start by making a list of things which you want to do and a list which you don’t want to do. Set your goals and work for them.
One cannot do it all, no matter how much you do, you will always feel less accomplished if you keep a tab on others. Social media is a distraction.
So you do not need to do it all but start by doing one thing at a time.
