For me, Well-Being is the ultimate success in life. A person who reaches a state of being comfortable; healthy and happy in life has a wholesome life.
Hard-work

It has been said over and over that hard-work and perseverance is key to success. However not everyone that works hard and perseveres is successful, depending how people measure success.
“Everybody wants to be famous, but nobody wants to do the work. I live by that. You grind hard so that you can play hard. At the end of the day, you will put all the work in, and eventually, it will pay off. It could be in a year, it could be in 30 years. Eventually, your hard work will pay off.”- Kevin Hart

Hard work alone without smartness and strategy is futile, for instance, some work very hard but shockingly achieve little. Work with others, be reliable and trustworthy respecting yourself and others around you. Trust is the mainstay of any relationship. To unfailingly achieve the desirable goals, one requires consistency of actions; principles or standards including openness; methods; measures (be patient and flexible when you encounter unexpected obstacles); expectations and outcomes. Taking responsibility and accountability of the actions wether good or bad. Express gratitude when others help you. Help others if you can, without compromising your health.
Sincerity
Have genuine honesty in whatever you do. Listen to your heart, connect with your inner feelings; thoughts; desires paying closer attention to your beliefs then act accordingly. Sincerity is vital in any organisation it helps in building trust among the organization as well as the employees. Making fruitful relationships in the workplace is one of the significant parts of work life.
