While the classic novel by Miguel de Cervantes of Don Quixote has many twists and turns, one theme is clear, that I think can apply to your goal of moving into or up in your Salesforce career as an Admin/Dev/Architect/Manager, etc.
If you want to be one, act like one.
Don Quixote was considered a knight-errant, where he would wander the land in search for adventure in his pursuit for chivalry.
Acting as if…
How are you pursuing your adventure on becoming a better Salesforce professional, especially if your current position isn’t allowing for additional growth?
How about going out and speaking to some of those who are where you want to be some day.
Asking about how their days typically play out, the types of projects and challenges they deal with, and advice to offer you to get where they are.
Then, take some notes, think about these, and ask yourself:
“What would an Admin, Dev, Architect, Manager do in this situation when you come across them.”
Psychologically, having these thoughts and actions could help build your confidence as if you’ve already played the part in your mind.
Be creative, be that Salesforce-errant. Just don’t fight any windmills.
“Thou hast seen nothing yet.” -Miguel de Cervantes, Don Quixote
