Often times, we underestimate ourselves and our ability to get things done because of the actions of others and how they have made us feel. But, God has gifted you with talents, abilities, and resources.
Those who question and underestimate your ability, it is they themselves who will miss out on the blessings and benefits of your work. Be confident in your abilities; affirm, and be proud of your work.
Invest in yourself, and take time to affirm the gifts God has given to you.
