See the list below.
To look toward what is good and what leads us to seeing what we admire and want to go toward.
To remind us of who we can be.
To remind us of how great life can be (and is), no matter what.
All of them, in a sense, inspire, as they give us more breath of life, so I had to artificially draw a line, where the inspirers are the ones who have (or can have) an incredible effect on our lives and our perceptions.  
Many have overcome things that put our problems into perspective, as little ones, not very consequential and very small compared to the joys of life.  
Many have focused so greatly on developing wisdom that they can lead us to much greater happiness.
When you need recentering, regrounding, or reinspiring or just a boost, ponder these people and what they've done and what they stand for. Read about them, read their quotes of wisdom...
Think of who you admire, are inspired by, who you would like to be like - and then find out what it is that they have learned - and you'll be who and what you want to be, inexplainably drawn by simply deep exposure to these greater views and the higher wisdom.  Post their pictures and you'll be drawn to being who they are simply by viewing their pictures.  
Write out who your top models are, by area, being sure to identify who has the characteristics and result in life who you can copy from their lives and be inspired to follow such a way of living!!!
How To Get In Touch With Who and What They Are:
Read books on or by them.
Go to YouTube.  Possibly some on netflix.com. 
Nick Vijicic - Born with no arms and no legs, yet he lives with "no limits".  Book Life Without Limits.
 W. Mitchell - Burnt all over his body and face, later crippled in a plane crash, not an inspirational speaker...
 John O'Leary - Burnt at 9 years old, 1% chance to live, now incredibly motivating speaker.  Watch all of the videos, under "John's videos" !  Proof of the power of the human spirit.  You won't give up so easy from a little discomfort in your life.
 Helen Keller - Blind and deaf, great author and lecturer.  She altered our perception of the disabled and remapped the boundaries of sight and sense...
 Michael Oher (Blind Side movie) - Book: "I Beat The Odds".   Be the best player, best person I could be... Success:  Food, roof overhead, decent clothes on my back. 
 Stephen Hawking - Totally paraplegic, totally awesome.  Zero-Gravity Video. "My expectations were reduced to zero when I was 21. Everything since then has been a bonus." 
 
THE ADMIRED - Of course, we do not profile all of these people here, as you can pop into the internet, seeing excellent summaries of the lives of the famous people on Wikipedia.com.  Read the best books, including biographies and autobiographies about them.  The asterisked people are on my list of people who I think actually lived good lives - see Great Men, But Did They Lead Great Lives?.
