You could, understandably, wonder why certain obligations or responsibilities come your way. But these aren't likely to be anything unmanageable. Sure, you might wish somebody showed a bit more proactivity or willingness to assist with something that they appear to benefit from as much as you do. But it might be necessary for you to take the lead briefly. There's no reason to resent this.
We often protect ourselves by adhering to a motto of, 'if in doubt, then don't.' Our instincts are usually worth trusting in this way. But as accurate and helpful as our inner voice can be, we can't 'do nothing' on every occasion. We mustn't allow doubt to hold us back every time we feel it. It's by ignoring doubt now that you could finally see a clear way forward with an idea or plan. Release that anchor!
If the urge to share insights or knowledge gained recently intensifies, then this isn't a time to hold back. You could be surprised at how easy it is to express thoughts creatively. But if there's a plan or project you're keen to embark upon, then accept that there's a potentially steep learning curve attached to it. This will need patience to get from A to B. As skilled as you might be in many ways, you won't be able to rush this.
