Habit forming — Writing on daily basis forces you to create a new positive habit. The ability to form new habits and establish new routines is a key ingredient of living a healthier more productive life. People generally fail at eating more healthily or exercising regularly, because they lack the ability to introduce a new habit / routine into their existing lifestyle. Writing by its very nature creates a record of how well your new habit is being established.
Perspective — Keeping a regular record of your thoughts and logic behind decisions is a powerful tool in building your business. We all know that leadership can be a lonely existence, you can take great comfort in reading how you overcame adversity in the past. Sometimes just the realization that you've been here before, is all it takes to get you over the finishing line.
