Getting the outcomes you want is possible
Desire is what fuels change, but alone it is rarely enough to gain consistent results when trying to solve a personal or relationship problem. As you know, life is busy and there are many distractions which interrupt even the best of our intentions. To achieve the outcome you really desire, you have to support your decisions with determination.
Decision - use your desire to fuel your decision to keep moving forwards. When you decide that you're absolutely going to do what it takes to achieve your ideal result, you will commit to following through on each step of the process even when you're feeling depressed, lazy or lacking in energy.
Determination - this is your drive to stand strong in your decision to improve this area of your life. So at the times your mind wants to lie, cheat and make excuses it is your determination to achieve your desire which prevents you from procrastinating about completing those tasks.
But you have to stop deceiving yourself
Watch out for these other common D's:
Distractions - we're in the era of information overload and constant to-do lists. If you need to complete a daily task that's going to improve your sense of wellbeing and your life, do it in the moment you think of it or another day will probably pass without taking effective actions to achieve your desired result.
Disruptions - know that you're always going to be disrupted by phone, email, friends, children or a partner. Stay focused on your mission! Be prepared to reapply yourself to those tasks which will help you achieve your desired outcomes. Deciding to do them later usually leads to forgetting them entirely, so don't put your future at risk.
Deception - it may seem like I'm repeating myself but as humans we are constantly deluding or deceiving ourselves. How many times have you decided to commit to improving an area of your life then not followed through with your actions?
Only you can initiate change in your life but you need to keep backing yourself with consistent action. It's better to take small steps every day than one massive step followed by a large gap of inaction. Self confidence and belief in yourself can be gained, developed, and enhanced by your actions.
