This is the place to be my friend! The knowledge you can gain here is priceless.
My suggestion is for your mom to think about what she is really passionate about - without the passion, it is difficult to maintain the drive needed to get up from your favorite tv show and go to work on the computer. I am 60 and that is what I have found ... we have a cat site because that is what my partner and I are really passionate about. Well, that and casino gambling but we ruled out the gambling early on due to the current laws in the US today. I am the computer geek in the house so it is up to me to balance between it being a fixation and being a healthy hobby. Unless, she really needs the income [like us-
] but instead needs a hobby to keep her interest and focus up, she should focus on the hobby aspect. And, one last thing ..., it can be literally anything!
Good luck to you and your mom
