One of my favourite things to remind myself is 'it doesn't have to be perfect to start'. Perfectionism is not a bad trait to have but the relentless pursuit and unwavering satisfaction will stop you reaching your goals and lead to disappointment in yourself and others.
Write a list. Look at what is important to reach your goal. Cross out the rest. Keep it simple. Often things will change along your journey. Trust yourself, your intuition and the guidance of the universe.
What is holding you back?
