What are good ways to earn and save money?

I am a 13 year old girl turning 14 in august. I already have 100$ in savings and I am planning on saving my money for summer and grade 9. How can I earn money in summer and save it as well and not be tempted to buy. I was trying to get a summer job doing odd jobs at my local either Extra Foods or Co-op House for Homes.|||You should always carry around pocket money, especially if you are 13. Maybe 15-20 dollars will do. Don't spend it all in one day but if your hungry or something, you can buy a bag of chips and a water bottle. It's tough making money that way. Try speaking to your guardians and ask them if you do stuff around the house will they help with your savings. Good luck!|||Invest in stocks through some trustworthy friend or colleague. Not the entire thing. Warren buffet started investing when he was 13.|||if you do come across money, try at least to save 5% of it
