Hey Tammy, that’s really a question every writer has to answer for themselves. For me, the most important thing is consistency. I am better at writing long pieces if I do a little bit every day. Like, half an hour. If you have more time, you can do more, of course. But the important thing is to work continually. Aside from that, there are many blog posts and books on this topic. I suggest you start there.
Companies like Uber and Lyft offer a great opportunity to make some quick cash. You'll need a clean driving record, a fairly new car and the authorization to work wherever it is that you live. If you have all of those things, you can work when it's feasible for you, whether that's in the middle of the day during rush hour, or in the wee hours of the night on a weekend. The choice is yours.
The ego is the driver making the decisions. It decides between the devil (the id) and the angel (the super-ego) on either shoulder (yes, all those cartoons you've ever seen are partly true). We have voices in our mind, and it's up to the ego to decide which one to fulfill. Its goal is to satisfy the id in some way while also attending to the super-ego.
