People who'd rather stay in their comfort zone like me always procrastinate (here, if you start your sentence with "people" you should use it as the subject of the verb "procrastinate" instead of using "I" in the middle of your sentence, otherwise it's confusing) and doing that makes me feel uncomfortable. However, today somehow I have done (a couple of such things => what does "such things" refer to?) and I just feel amazing. I can finally think about other things and I feel a bit more free.
