Also, what is the difference between being resourceful and self-sufficient?
If you do, then the result will only be misery and suffering. If you adopt wrong means to earn money, then your own conscience will prick you from within, and you will feel, 'I have stolen from someone'. It will pinch you from within.
So do not use wrong means of earning money. You should put in all your effort to earn money, making the best use of time available to you.
