Also importantly here is to set yourself small goals, which will help you achieve your dream in future, for example:
Create a project where you can control things with mouse/keys/touch. Throwing balls, dragging items. Work out how to create an inventory system, and use dictionaries and arrays to store information and retrieve it.
Play around with the tilemap and other different types of objects, to learn what they do and how they work. See project examples given with Construct.
Get to know the behaviour plugins, they will save your life many times (such as the pin to behaviour, wrap around, physics and everything)
Overall getting to know construct will save you thousands of hours for a large game project.
And there is always the guys here when you get stuck on something!
Good luck friend!
