Consider buying better quality products for yourself instead of only buying them for others.

Take care of your health. Exercise, take supplements, cut out sugar, but don't beat yourself up if you have a treat on occasion.

Make the effort to create a pleasant space to make you smile. Declutter and order your environment the way you like it.

... for yourself every day.

Letting your blood sugar sink sends stress signals to your brain. 

Avoid tying yourself to clients, business partners, investors, or employees who make you unhappy. 

There's no reason to put up with people saying or doing things that constantly break you down.

Working in dark spaces is very unhealthy. Try to change your environment to gain access to natural light, or invest in full-spectrum light bulbs. 

Above all, make sure to get outside for a walk as often as you can.

We often criticize ourselves in our own heads and that damages our confidence.

Refrain from talking to yourself in negative terms. Know that you're good enough.
