Instead of fizzling out, things can also flourish, thrive, or succeed. To flourish means to grow or develop in a healthy, vigorous way, while thriving suggests not only growth, but also success and prosperity. Success can also be achieved by persevering or persisting, which means to continue despite difficulties or obstacles. Alternatively, something can end abruptly or explosively, rather than fizzling out, such as with a bang, crash, or explosion. The opposite of fizzling out is not just limited to maintaining vigor or reaching a desired outcome, but can also involve sudden, unexpected endings or transformations.
