You have to believe that what you're doing right now has an impact on your future, and you have to be confident that even if you're leading the way, it's going to be extraordinary.
Your job will take up most of your life, and the only way to be truly satisfied is to believe in what you do and love what you do. If you don't find it, don't give up and don't stop, try your best, just like all great relationships, things will only get better with age.
Time is limited, and you should not waste it living someone else's life. Don't be trapped in dogma. Don't let the noise of others' opinions drown out the most important thoughts of your inner voice. Take courage, listen to your inner voice, and follow your own feelings. These are the things you want to achieve, and others are secondary. Be curious and open to acceptance.
