You can answer that question more accurately than I can because that honestly depends most on you. When thinking about how long this service may take, I like to explain it partially like a stoplight or an old red-yellow-green dial/gauge (often seen in a movie connected to something that shouldn’t go too fast or too slow or get too hot or blow up).
Most of us have goals that we would put in the green zone, they are big, they are positive, and they are changes that we believe we are ready to make like hitting the gas when the traffic light turns green. But before we can get to green and hit the gas, before we can go, we need to make sure we’re at baseline or neutral (yellow) and have 4 working tires and an engine that runs. Before we can really get into being at baseline or moving slowly, we have to triage, repair, and replace whatever has us stuck/stalled/flat in the red. Then even once we do all that, great results are greatest when they’re repeated consistently, and that in itself takes practice, support, and repetition as well
