Make the Most of Your 24 Hours

Bitter Experience

I wanted to make myself stronger, earn more experience. I had a misconception of working and learning. I thought, freelance projects will help me strengthen my knowledge and experience. So I tried to get as more as possible freelance projects. And my nightmare started from here.

I had no time to spend with my family, no time to work on personal improvement, no time to go out with friends, no time at all. All of my time was used up on my freelance work from coding new features, fixing bugs and much more. I was killing myself working odd hours and missing out on quality time with my family and friends.

I made a mess, uncountable technical debts, bugs, with the project. I was angry with everyone and myself. And the company project was affected. I brought more bugs there, dozens of stupid bug
