First steps to take?

I am 19 (February this year), I currently work, I am interested in business (always have been). That brings me to the question what are the first steps to take that I need to do? The first step is always the hardest and even harder when you don't know where to put your feet!About me - I like Football (play at a decent standard not far off part time money), I like watches (buy, refurb, service them), I like the outdoors, I like indoors and technology (built a PC, and quite tech savy if you like).Ideas? - I've had/seen many ideas yet haven't even taken the first step in most cases. These ideas/methods include, dropshiping/e-commerce, real estate wholesale, POD clothing brand, online courses, affiliate marketing, watch brand, and a few more.Steps? - the only idea I've taken the first step in was the POD clothing brand, I made a goodish design and stuck it on a jumper, and ordered one myself. The outcome? Rubbish, wouldn't even dip so low to try and sell them, now the blank was bad because I cheaped out but the print didn't even come out nice. Still a possibility? Yes but I feel you need alot more disposable money for the trial and error phase considering it could cost anywhere from £15 to £50 for a single product sample.Most interested idea? - Affiliate marketing, (seems to be good money if done right, but may be BS as a lot of online courses get sold for this). Retail wholesale, (one deal is big money, seems to be hard to get into and quite complicated).End goal? - freedom. But not just from these businesses/side hustles. I want to get enough money to start a rental business, do the houses up and rent them out. Nice steady monthly income from a generally appreciating asset. Now this seems to not be particularly that hard of a Entry barrier near me, you can get houses in need of TLC for as little as £60k and these still rent out (when done up) for £650-£850pcm. And then eventually with the purchase power and experience gain entry to bigger property (apartments, retail complexs)But for any of this to mean anything I need to take the first step, and I dont know where to place my feet, people in my area and around me don't think of anything but the regular 9-5 (nothing wrong with that) I just believe there's got to be more, the chance of you being born and to just accept to be another person on a spreadsheet is well depressing I suppose.Any help, tips. Much appreciated thanks. see hubwealthy.com/wealthy
