Assalamualaikum and good day,
We desire success every single day. That is why we push our self to do many things at once to speed up the process of being success. For instance, having office job during the day and doing food delivery at night.
However, the reality is, we will most probably not achieve success because successful people only focus on one thing. By focusing on that one thing, successful people grab that once in a lifetime opportunities when it comes,
There are many successful stories are based on this. Read the story of Jack Ma who focus only on e-commerce, Colonel Sanders whose focus is to sell his own fried chicken recipe and many more.
Hence, there is a million possibilities of being success, but the real opportunities only given once.
