motivation

Nobady can deny that motivation is something very important for us to acheive our goals. So if everyone found motivation and encouragement it would be easy [for him to get what he want...]

General Notes:

--Encouragement is the noun form of encourage. Since you said 'motivation' and you are including additional factors, they would also be nouns within a list.

--I'm unsure of what your final statement is meant to imply. Your sentences all speak of 'us' and 'everyone' but your final statement refers to 'him/he'. If you are referring to everyone, the final statement would be more like "...it would be easy to get what we want."
