I have a simple direct answer I give to anyone who asks me how to be successful in life and that is "Be yourself". You can't be successful when you try to be someone else. Now apart from being yourself you also have to

Believe in yourself

Have a plan

Follow your plan

Be determined and focus

Persevere when trials and hurdles come because they must come

Be resilient

Be willing to take risk

Try out new ideas and innovation

Do not limit yourself

Listen to everything people say but filter and only choose the positive ones

Make friends with goal oriented people

Read books on how to be successful

Be hardworking

Above all, be prayerful.
