"However long it takes you to reach your summit, just keep walking and don't think about it." ― Roberta Vinci
In life, you need to believe and care. Care for yourself and care for others. Be selfish and be selfless. Find a balance and be a well-rounded human being. We are not perfect. We cannot strive for perfection. Instead, work hard, be nice, try your best, don't give up. That will lead to your success and hopefully, happiness.
I don't know if I'll ever "succeed" in life, but I know I will not give up on myself and my dreams. I am nothing without my dreams and passion. I have the willpower, strength, drive and motivation to push myself to the ends of the universe.
There is no limit. Climb to the highest point, the summit. Climb. Climb. Climb. Breathe. Breathe. Breathe. Strive. Strive. Strive. Love. Love. Love. This is my mantra.
