It is ironic when a self-employed person claims that he doesn't have to worrying about medical certificates, CPF or other corporate concerns. On the contrary, he should be concerned that he has no MC whenever he falls ill since he still has to cover his cab rental or CPF since he is self-employed. As for corporate concerns, doesn't he miss delegating work to subordinates since the buck stops with him now? 

He is saying these things to comfort himself.

Likely he cannot stand working under certain bosses and decided to leave. Once the decision is made he self reinforce to justify it to make himself feel he has done the right thing.

It's like people who made certain major choices in life choosing work overseas or certain jobs then they justify it was a good decision because of this and that. But they never consider how things can also turn out well if they hung on to other choices.
