"Little kindness and courtesies are so important. In relationships, the little things are the big things." —Stephen Covey

In long term relationships, it's the little things you do for each other, day in and day out, that mean the most. They are a way of reminding your significant other that you care, and that you're thinking of them. They are a way to show your appreciation, and to remind your best friend you love them in your every day life. Little things you do for them make the biggest difference in their life — and your relationship.

Here are 33 little things that you can do to strengthen your relationship:

1. Playing their favorite song in the car when you know they need a pick-me-up.

2. Making the bed.

3. Cooking their favorite meal.

4. Compliment them.

5. Write sweet and random notes, and leave them in unexpected places.

6. Have a TV show that you only watch together.

7. Always show your appreciation — remembering to say "Thank You," for the little things will get you far.

8. Celebrate each other's successes.

9. Back scratches.

10. Make 'movie nights' a regular thing.

22. Spend time away from your phones.

23. If you live together, try to always go to bed at the same time.
