A good idea will change your life. Funds, stocks and lottery tickets will definitely not work, which will only make you more depressed. Besides, although big business makes a lot of money, you have no capital.
Personally, I think the elements of making money are nothing more than the following:
Either you have connections, and you can do what others can't;
Either you have a lot of money and can take over goods that others can't.
Either you are very creative, and you think of something that others can't.
If you have to wait for money to get married, you'd better borrow money from your friends first and then pay it back slowly.
