Interesting!

Friends can be a great source of encouragement to you and their encouragement can really boost your willpower to improve yourself and increase your chances of attaining success.

That's very true. I can recall a particular moment in my life where I had lost hope and almost totally resigned to "whatever life dealt me with", my friends would encourage and urge me to keep pushing and pushing. They'd often tell me I am closer than I think. And they were right, because explosive success was the end result. Perhaps I would have given up and lost out on attaining what I had set out to achieve.

Good motivation. Thanks @kenny-writes
