Success doesn't have a single definition. Some may define success as simple as attaining a desired goal, while others have bigger definitions, such as realizing hopes and dreams in life. Becoming successful is a turning point in one's life. There is no better way on how to enjoy success than to share it with others. Success is a blessing and blessings are meant to be shared. Be aware of the people that have helped you attain your ambition by being grateful.
At the end of the day, the people that surround you are those that matter. Enjoy success with these people by being thankful and spending more time with them. For example, a person who is too busy working hard may have sacrificed their time with their families and loved ones at one point or another. Once a project is over and becomes successful, spending more time with family and friends is a good approach on how to enjoy success. After all, these people have supported you all the way and never left your side during the duration of the project.
Having a work-life balance may be tough and requires excellent time management skills. It's easy to become successful at work, but you usually have little time left for your social life due to long hours spent in the office and vice versa. Self-help books might have skipped this part. At the end of the day, this might be the right formula on how to enjoy success and become fulfilled and truly happy.
