Affiliate Marketing Secrets

I’m ready to learn and do what ever needed to start my own business. I just want to know how. Last few days besides job I spend of thinking what kind of business I want. I understand that I want financial Independence and for me its doesn’t really matters in witch niche to start.
I have no lots of money so any possible cheap business is fine with me. I just want to spend my time for better future for me and my family. That is my motivation. I want to be a better man.
I looked for possibilities to earn from offline affiliate, my plan was to advertise trough flyers in the evenings but I didn’t find anything that would work. Or maybe I’m just too scared to try.
So if you have any information where i could find usefull information or motivation for start, please share you’re knowledge.
Great would be to know some schemes that work that would help me to rise funds for better businees.

I need some help figuring out what I can sell on a website I want to create. I do not want to do affiliate programs, and all that..I want to sell actual products. I am 17, and I am into military stuff (i.e. guns, gun accessories, military apparel, military accessories, etc.) I am also into video games….but take note…again I am 17 YEARS OLD…no expendable/disposable income…NOT A LOT OF MONEY. Any cheap business ideas for a 17 Year Old would be appreciated…tanks.
