"A începe este ușor."

Translation: To start is easy.

[Schattenparker]

For German/Dutch speakers:
This is literally an-fangen/aan-vangen! ("on-catching")
since începe has the same Latin roots as capture (capio)

English natives may know the word "incipient" for beginning...

[vincemat]

A începe este DIFICIL

[MotherEffi]

A continua este dificil. Not sure if continua is correct.

[MichaelLongspear]

It is.

[AgonizedCat]

What does "to start" even mean in this context?

[IngunnW.]

Highly depends on what you're starting or starting with. It's easy to start a fire, indeed. A positive change, though - not so much
