Thinking through this topic, I see that a large percentage of motivations that come from motivational speakers - especially individuals coming from different fields of career - can be misleading. This is mostly because most would either exaggerate or belittle the context of the situations being discussed.
Imagine a professional public speaker telling a bricklayer, carpenter, or a farmer that he shouldn't rest when he's tired, but rather he should rest only when's he has completed his job. If they listen to that kind of motivation, they might not live to come to work another day.
Similarly, there are some clergymen that will tell you that all you need to succeed in life is the word of God. Hmm, that may be true if your success is a kind of manner that will fall from heaven, or if you are also a clergyman. But to succeed in another profession in life, you need adequate training and knowledge of your work - not Bible knowledge. Now, I know there's a place for asking God for wisdom and divine knowledge about your chosen profession. But more importantly, I think you need training and mentorship by the people in your area of career focus.
If you are in Business, you need to know how business works! If you are a scientist, you need to know what it takes to carry out groundbreaking research, and if you are a student, you need an adequate understanding of what is expected of you in school. Stop listening to people that will mislead you. Go to the right source for the training you need. Go to the people who have done or doing what you want to do.
If you want to be a writer, listen to, and learn from writers. If you want to succeed as a politician, go and join politics and study towards that line. To be a motivational speaker, listen to motivational speakers, and to be a pastor join a church leadership and get training that will turn you into a successful preacher.
It's nice to be a strong Bible student as a Christian, to enable you to understand the spiritual approach to life challenges, but after that, except you are planning to be a gospel minister, please spend more of your time on the career you have chosen in life - that's your own call in life. And if you think your call is to be a preacher or life coach, please spend more time with people in that line. Stop wasting your time, hanging around a building you will never enter. Focus on your own direction and move towards your own destination.
Let me say it again. When it comes to getting instructions and motivations regarding your profession, seek them from people who have walked or walking in the same pathway you are. Don't let the people who have never been in your shoe tell you how to wear it, except you are ready to play try and error with your life.
Here is the bottom line, the summary of my thoughts. Be selective and careful when it comes to listening to motivational speakers or even some so-called pastors. Only listen to people that speak from personal experiences that are related to your direction or potential direction. A wrong motivation can make you live lesser than your potential. It can also make you break your backbone. But right counsel will direct you in the pathway that will lead you to a destination that is best for you.
I don't think you will get the best from a professional motivational speaker, a clergyman, or any individual teaching you what you need to do to succeed in a field they have never practiced or trained for. It would be like getting a random person to read a coaching material and coach a football team to succeed.
