Research suggests that up to 40% of our day is spent acting out existing habits rather than making new decisions. 

From sleep to personal hygiene to diet and exercise. 

Some of our habits serve us well. 

Others can be more complicating. 

If you want to change a habit, behavioural scientists suggests starting small. Make one minor adjustment over time, it creates a domino effect that helps us make bigger chances down the line. 

Make a radical change and you've set yourself up for failure. 

The principle of the domino effect is a double-edged sword. It can help us build healthy habits but it can lead to destructive tendencies as well. One small misstep becomes one bad habit. 

Of course, none of us is perfect and so much is out of our control. 

All you can do is make the best choices available to you and hope they don't come back to bite you.
