"Just be consistant" is not enough. To improve any skill it takes multiple factors and practice is one of the biggest factor but not the only one.
If you want to improve any skill you should study and practice for it. If you can take classes then do so. If you can't then investigate and try asking for advice here and there. Ideally ask for advice with teachers who know the subject. An experienced writer can help you but being experienced in something doesn't mean you can be good at teaching it.
You shouldn't rush. To become an expert at something it usually takes over 10,000 hours. Rushing may get you those 10,000 hours faster but it can also deminish the quality of work/practice you put in those 10,000 hours.
It's not the same to bake a cake in 1 hour than it is to try to rush a cake and do it in 1 minute. If you do it like that your cake will be either raw or burnt.
You seem young so keep practicing and do look for guidance from an experienced teacher. You will also need to read a lot in order to learn from previous writers.
