Nothing can stop the man with the right mental attitude from achieving his goal; nothing on earth can help the man with the wrong mental attitude.
If you're trying to achieve, there will be roadblocks. I've had them; everybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.
I just think a hustler's ambition is that I never stop. I start off hustling and said I'll never stop hustling. An ambitious hustler is the one to hustle the hustlers. When I grew up, my heroes were hustlers. Now I'm their hero.
By taking the time to stop and appreciate who you are and what you've achieved - and perhaps learned through a few mistakes, stumbles and losses - you actually can enhance everything about you. Self-acknowledgment and appreciation are what give you the insights and awareness to move forward toward higher goals and accomplishments.
