You're worrying too much bro, stay calm and stay focused, first you need to identify a profitable niche for yourself on which you can work aggressively to promote your store. Then you should find some trending products to sell online in your niche that can give you maximum profits.

But do remember while doing dropshipping business it is pretty crucial which product you choose, because if you are choosing the product with low competition (which means there is something fishy about that product thats why competition is very low) then you will not be able to make profits.

Go for your country first as it will allow you to learn and earn simultaneously.  

Doesn't matter what business you do, you have to know each and every thing from the Grass root level.From business name to business growth and prospectus to all the legal processes you need to go through. Apart from all these things, the main point is that you need to have patience, patience is the vital key in starting and running the business. Don't expect quick results, business that give quickly doesn't last for long (majority of the time). Build relationships with industry leaders and influencers. Make them talk about you wherever they go. Believe me it will help you in boosting your business.

If you want to achieve something in life you need to work hard for it.

That's how I motivate my self.
