Hi Munur,
My biggest tip for you is to avoid the shiny diamond syndrome. Shiny Diamond Syndrome is the tendency to be constantly attracted to new projects, ideas, or goals, often at the expense of ongoing initiatives, leading to a lack of focus and unfinished tasks.
One skill that is still highly needed is good Google Ads marketeers. People will always be searching for a solution to their problem. Google is that middleman. Become good at that one skill and you can easily sell that as a service to others or use it for affiliate marketing or many other things.
If you're really want it you can become pretty decent at it within 4-6 months. Take a couple of hours a day to gain knowledge. There is loads of free content on youtube that you can leverage to gain the knowledge to become good at it. I learned everything I know about Google ads from watching youtube videos and Googleing some stuff.
I recently wrote a post about Google ads here on BHW.

That being said, this knowledge applies to anything. Whether its SEO, Social Media Advertising or any other thing, keep at it until you become good at it. The best thing about learning one skill is knowing that the knowledge is transferable. So knowing a lot about Google Ads will make Social media marketing easier, will help you with SEO, etc... but the first step is to become good at something and that takes focus.
PS: you don't live in a "third world country". There is no such thing as that. You live in a country with lots of possibilities and growth ahead. Third world country is just a stupid name western countries made up to make themselves feel better. Go be great!
