What is meant is that one should take care for the things they already own and learn how to use them to make more.
1.Winning and gaining is what am in this life for
No, a common mistake by the current generation. Your aim in life is to be a good human being.
2. Gaining will make me more relevant in all endeavors than to loose
Losing is a part of gaining. If you never lose then you are not taking a risk. Failures are a part of life. Start looking at them as lift lessons/turning points.
3. For me to get engaged in many things, then my mindset is determined already on gains
If you remain infatuated about gains, you will likely lose your sanity over those things. The world is much more than just your gains. Being able to use your money to get more money is a good thing an that is what everyone is doing but that should not make for forget the little things in life that make it all the more beautiful.
4. I say yes to the pains because no pain then no gain, therefore I should have more.
In the context of life, pain is important because it teaches you a lot.
