Do multiple things or do only one thing?

Lately, I have geared up myself to do multiple things. I purchased a house, I set out to start a small company that sells products online, I have started exploring learning opportunities in Data science field, I have been playing an active role at Toast master club all while being a parent to two young kids (2.5 years and 0.5 years/) and with a full time job at Swiggy. I could manage to do make progress in all these endeavours (Sometime, I had to stop going to Toastmasters sessions as travelling was taking 1-

1.30 hours) because of support from my family, friends and my colleagues. Just about the time I was getting a groove of doing multiple things at the same time, Swiggy laid off 380 people that included me and my team.

Here I am without a job but with a lot of other activities going around me. As someone who needs a full time job to fulfill financial duties, I am scrambling to find one. In the process, I am wondering if I need to drop my thinking of doing multiple things and focus only on doing on the job. In my work, I never neglected any of my duties. We were working on needle mover projects for the organisation. My team and I were meeting in office regularly, I have taken important parts of the project such as building business P&L, owning the execution plan document. We have been working with our senior colleagues closely and have been setting up reviews with leadership. I had a feedback from my manager that he sees a visible change in my approach in working with my team from last quarter in the sense that I have started leading from the front instead of supervising the team. I had an opportunity to work with CEO for the first time I joined the company. But then, we got fired. 

I wonder if I had not spent time on identifying a home for ourselves or starting a business of my own, would I have had a chance to keep my job? I really don't know the answer. I could have probably found out another job within the organisation a little earlier? Not sure if I wanted to do that because I have only been in this job for 6 months. 

My wisdom tells me that sometimes  circumstances are beyond our control and what's important is to ensure we give our best in terms of adding value. If I can understand my strengths and focus on areas that I can contribute to where win - win can be delivered, things will fall in place. Ofcourse with the help of almighty and parents blessings
