1000 $/day done! Now what?

Hi guys,
these days I’ve reached 1300 - 1500$/day and I’m really excited because this is the first time I’m seeing those huge numbers that defeated all my expectations. In this situation, I’m trying to keep lucid and rational and I want to get some advice from people who have passed through these numbers. My questions are:

  1. Is it advisable to invest in a startup company with let say 3-4 persons to make more apps? Have anyone done it? What are the results if you can share some data?
  2. Should I go instead for investment in real estate or any other thing not related to programming?
  3. Should I keep my solitary work as an android app developer and enjoy my life?

Maybe some of you made these decisions before and I want to know some decisional mistakes that you regret or decisional success that you are proud of. Many thanks in advance.

  1. Is it advisable to invest in a startup company with let say 3-4 persons to make more apps? Have anyone done it? What are the results if you can share some data?
    Answer: it advisable to invest in a startup company with let say 3-4 persons to make more apps only If they focus on quality over quantity. having a huge app with above 100+ Million downloads. If you think an app can get 100+Million downloads then only invest there.

  2. Should I go instead for investment in real estate or any other thing not related to programming?
    Answer: Yes you can go into real estate for passive income for lifetime. And u can do any other business(can be non programming) which is best known in your city. Like my city is best known for handicraft furniture industry of the world. Doing traditional business for your area will be the best boost for you.

  3. Should I keep my solitary work as an android app developer and enjoy my life?
    Answer: You can but your apps may not last more than 5 yrs from now. If you are young, your zeal for earning is to chase girls, its ok. But you cant go above 1500$ per day in my opinion because you are Self Employed. Get involved in a big company will give you exponential increase in your earnings from now
