R is for Resistance. Resistance is your negative thoughts and feelings. When you make negative thoughts you will have negative feelings, negative feelings will lead to more negative thoughts. That will build your resistance. If your resistance is too big there is no way you can manifest what you desire.
Resistance can be dealt with by letting go. You can meditate, go for a walk, go for a jog or take a nap. Any way you can lower your resistance towards what you want will allow you to retrieve it faster.
There is a chance you can improve your emotion, intention and focus enough for you to achieve what you want. However, life gets much easier if you lower your resistance.
Learn how to relax, have fun towards your goal and lower your resistance. Then you will energize your ability to manifest!
