I experienced being weary of pursuing my goals to the point of giving up. I was filled with anxieties as to what the future holds. Then, I decided to shift gear and refocus my lenses to the very reason why I am in here in this world.
There will be obstacles along the way. From difficult people but you will learn most from these people. You learn patience, you will lean to arm yourself with courage and diligence.
Also, have a dose of positivity everyday. Remember the three idiots with their "All is well" mantra. You will lose nothing if you will embrace the same. Know too that what the mind can conceive, the body will achieve. If you conceive being successful... Then be successful.
Allow yourself to be surprised. Life is full of surprises. Bask in the wonders of what's come. Be excited, be free from the "what ifs" and welcome all the possibilities. From there, live your life one day at a time with these elements in your system, then everything will turn out fine.
And never be discouraged for "All glory comes from daring to begin"
Finally, I urge you to find your niche your perfect place in the world thay only U can fill.
You've written well, Success depends on one's self. He decides to become successful or not then employs strategies to make it a reality.
