Make sure you learn, think, say, do something new everyday. Stop comfortably living in the past, except for being grateful to God, parents, authorities, and those few great folks who touched your heart, head and transformed your life. Other than for gratitude, never stay in past; move forward in knowledge, wisdom and wait, welcome new revelations from God as well, live in newness. Life is short, live fast, cherishing every moment and remaining fruitful and productive.
