This is a mental game. Sticking to a new habit is purely to do with the mind, and you are in control. That's the thing to remember.
You've got this.
That said, it doesn't always feel that way. So it's always helpful to have someone who you can count on to keep checking in with you and encouraging you to stick to your resolve when the going gets tough. It can be anyone; a friend, member of the family, or a trainer. You've got it covered, you really do, but having someone who cares about your achieving your goals as much as you do, who you can depend on to have your back when any doubt kicks in, is invaluable.
Remember, this is a long term change, so don't pressure yourself into being perfect 100% of the time. If you miss a workout, or have that bag of crisps you promised yourself you wouldn't eat, draw a line under it. Don't let it become a slippery slope to self sabotage. Change is a bumpy road, and life is chaotic, so allow yourself to roll with the punches and don't get stuck in negative, self critical patterns just because you're human.
Think long term. Think sustainable progress. Think accountability. Everyone misses a workout every so often, or has an extra slice of cake they didn't intend to have. The difference between people who are fit and healthy vs those who are not, is how they handle those blips.
Believe in yourself. Cut yourself some slack. Call on your accountability partner when you feel your resolve weakening. And remember, you're improving, every day. Just keep going!
