Start now.Usually when we're going to make a change - like working out regularly - we tell ourselves "I'll start Monday" or "I'll do it tomorrow." It might start with good intentions, but we rarely follow through when we think we can just do it later. Start now! You don't have to immediately start running a mile, but take a walk outside or a short jog when you get off work. Starting now will help you get into your new habit and stop you from making it a "someday I'll do it" type of dream.
Leave the past behind.Maybe you've tried to quit drinking soda before or you've lost weight only to gain it back (I don't know why all these examples are health related so far). Don't let your past failures keep you from making a change. Or maybe for you this means you're a shy person and the last time you tried breaking out of your comfort zone and meet new people, you felt super awkward or didn't make any new friends by joining an organization or something. Don't let that stop you! Maybe that just wasn't the right setting for you or that person just wasn't looking for a new friend. Start a new and leave the past behind you.
Get into a new mindset.You can't make a change if you're still thinking the same way. Use a quote or photos to inspire you, make a vision board - either on Pinterest or on paper - and get into positive thinking. Know why you want to make this change and remind yourself everyday.
Allow yourself to make mistakes.Whenever you're starting over or making a fresh start, it's only natural that you're going to make a mistake or relapse. When you make a mistake, admit it and own up to it, but don't let it completely derail you. Making a mistake doesn't mean you've failed, it only means your human. So if you're trying to wake up earlier, don't let hitting the snooze button and running out the door in a rush mean you're done waking up early and having a calm morning. Set that alarm for tomorrow and get up with the sun! Making a mistake might also let you know additional changes you need to make - go to bed earlier, set 2 alarms, or turn a light on first thing in the morning.
In my mind, the hardest two on this list are the middle items - leave the past behind and get into a new mindset. These are the ones that require you to change your thinking and let go of some things that may be difficult.
