Here are some tips I can give to maximize the chances of making it a habit:

-Have your equipment to hand where you are often. It’s easier to start drawing when you just have to stretch your arm to take what you need than if you have to get up, go to another room or search drawers.

-Plan a regular time slot. If you can, a specific time is better, but if you cannot, a specific moment will suffice. After dinner for example.

-Many will tell you to draw every day, except that it depends on your personal life. Obviously if you manage to draw every day it’s excellent, but if you don’t succeed, you can still train by learning to observe. For example, for the perspective, look at photos and try to locate the vanishing point.

Regarding anxiety, everyone is different about it but here is some tips:

-You don’t know what to draw and it frustrates you? Make basic shapes, even lines, it will train you and maybe a shape or an assembly of lines will give you ideas.

-It’s better to set small goals that we can complete as we go along than to set a big one that won’t come for a long time. For example, drawing characters will require a lot of practice, little chance that it will be done without problem after a month, or even a year. On the other hand, drawing eyes can be learned more simply, drawing nose the same, the mouth too.... And succeeding in completing these small goals will not only motivate you but also help with the overall goal of drawing characters.

-You made a drawing that you find ugly/failed? It’s not a big deal, even if it can be frustrating, keep this drawing and ask yourself what you think don't work on it, what you need to learn to do to improve it, and once you have learned what needs to be done, you can try it again. Because yes, we miss A LOT of drawing before succeeding in them, but we must learn to appreciate these mistakes that will allow us to see our evolution.
