No great person ever achieved greatness by being content with what they already knew. They became even greater when they did not stop learning.
Same applies to you dear singer. If you want to stay relevant in this industry/ministry, you mustn’t stop developing.
Challenge yourself and venture into new areas, whilst working on your weaknesses. E.g. If you’re good at high pitching, work on your low notes and be a master at that too.
Research about new things happening in the industry/ministry.
Attend workshops and training sessions that will enhance your craft.
Network with industry players.
Look for opportunities to use your gift.
And finally, Practice! Practice! Practice!
