Commitment is the key to anything you want to achieve. Sometimes even more than you can dream.
However, goals are hard to reach. In most cases, results are not driven by us. We can not control it.
If you want to be a successful salesperson, you need to focus on the number of people you can reach out to per day. It does not matter you close to the deal or not. You commit to what you can control.
Or, do you want to be a great writer? Just write every day. Forget about the results who will pick your writings and publish them as a book. Just write every day.
Ask yourself what do I control on my commitment to take me to whatever level I want to be?
