First of all I'll start with a phrase my dad normally says "the world won't get soft just because you're" or "everything won't become easy for you, just because you want it to be easy"...and these lines always come to my mind, especially when I'm trying to procrastinate something or when I'm being lazily reluctant to do something.

People may see you weak physically, and conclude you're worth nothing, but I tell you something, the state of your mind is your true strength, not your physicality. And you don't have to go about trying to prove people wrong, or trying to change people's perception of you, because if that happens, then you're using your precious time for something else.

Proving people wrong about you is not something you suppose to be putting your mind and time to, rather doing what makes you happy and successful with your time is already a prove of what you're capable of, you don't need to base your mind on people's thoughts about you, because if you should be in their minds, you'll see that not all of their expectations for you are good.

But if you use your time to continue doing what you do, the results of your hardwork is enough to speak for you.

Time:

Time on the other hand is another big factor for progress, and bringing out the best in whatever you do.

If you look around you, you'll see many people who have made it far and successful in what they're doing, and then you feel oppressed or fell like yours is taking time or is just a mirage, but what you have not done is ask that successful man or woman how long did it take for him/her to get to their current position...because if you do, you'll know that nothing good comes speedily, it all take a lot of your time.

So, if you're putting your time to something, it better be worth it, as you would not want to waste your time on something that doesn't keep you happy, or the end product isn't beneficial to you or anyone around you.

Nevertheless, if you put your "Mind" and "Time" to something good and beneficial, and it hits a dead end, or it doesn't play out the way you imagined it, that's not failure on your path...that's learning, and once you develop extra knowledge about a particular thing or area, you become more experienced in that area.
And it becomes easier for you than when you first started it...REMEMBER, good things take time.
