I use to say this more often to people around me, that if you want to help a person in life, then learn to know and identify the strategic place of need in such persons life and fixed it, if you give them bread, they will soon eat it up and be hungry again, but when you make decision in alleviating them and helping them to start an investment that could be profitable for them to depend on for financial survival, they will always earn through such instead of coming back to you for more help.
Know the person’s weakness and help him encourage to overcome it. Teach him to stand on his own foot and not to rely on other person, and by helping him land on a stable job or a reliable side hustle or investment, you are just giving him opportunity to grow and support himself, without feeding him everything he needs. That way, you did invest yourself onto him but in a productive way.
It's as simple as that. You revealed what'd be best and productive to him as you exposed him out to the field where he can actually be nortured and certified to self reliance of making incomes of his own instead of coming to you on basis asking for your assistance.
Even, those little demanding assistance from him can cause distractions to your pursues but if you can get him settled and focused to himself to a source of providing for himself, of course that'd enable you too to focus more undistractedly towards your goals.
