Be clear on your goals: pick the method that will work for you to crystallise your goals. We like vision boards and scrap booking; meditation or soul-collage (basing your collage on intuitive choices, words and images you are drawn to, rather than concrete items). It might be that you keep a journal for a while, or speak to a confidante at length. Whatever it is, start to formulate where you want to be in 3 months' time and beyond.
Start your day with a mantra: You become what you say to yourself most of the time. Your affirmations must be positive and in the present tense. When you make an affirmation to yourself, you are confirming the truth of the statement. Pick something that links clearly to your goal, and practise saying it to yourself. You can display it somewhere, but be sure to always say it aloud.
Make a plan: begin the day in a proactive way, by making a plan. Remember to set aside time to respond to others' requests of you, and give this a time limit. This gives your day an altogether proactive flavour, rather than reactive, which can leave you chasing your tail and focusing on others' priorities. Ensure you allow time to work on your goal. Makes lists, keep a diary, leave notes for yourself around the house: whatever it takes to keep you on track with your plan.
Have an accountability buddy: Make yourself accountable to someone. Some people use social media as an accountability measure, finding it helpful to announce their plans to run the next marathon publicly. If this is not for you, enlist a friend or family member who either has a similar passion, or an interest in seeing you succeed. Update them regularly by phone or text. If you can find someone to train with, even better.
Keep a journal: Take a few minutes as often as you can at the end of the day, to reflect on what went well and what you can work on for tomorrow.
